Status Services Overview (Group 0)
Live network-introspection commands used for connectivity checks, version discovery, statistics, and auditing.
Overview
Group 0 is the live status surface. These commands do not move value; they expose reachability, versioning, operational metrics, and audit-oriented reporting. They are the safe diagnostic primitives that every RAIDA implementation must answer.
Per-command wire formats live on dedicated pages linked from the sidebar: 00 echo, 01 version, 02 show_stats, and 03 audit.
When to use Group 0
Use echo for cheap liveness probes — before expensive multi-RAIDA work, or to drive a dashboard’s online/offline indicator. Use version when you need to gate feature handling on cluster rollout state. Use show_stats for operator-style aggregated metrics. Use audit when you need reporting-grade output; it is intentionally distinct from show_stats and its response shape should not be assumed compatible.
None of these commands authenticate against a coin AN. They are pure read endpoints.
